WILSON O. BERGER, OF CANTON, OHIO, ASSIGNOR TO THE BERGER MANUFACTURING COMPANY, OF SAME PLACE.

SHEET-METAL ROOFING.

SPECIFICATION forming part of Letters Patent No.'505,021, dated September 12, 1893.

Application filed October 15, 1892. Serial No. 449,030. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILSON O. BERGER, a citizen of the UnitedStates, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Sheet-Metal Roofing, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to an improvement in sheet metal roofing, and consists in providing means by which the wide upturned flange of one of the sheets is secured to the anchor, before turning such flange with the anchor over the narrow up turned flangeof the adjoining sheet.

With these ends in view my invention consists of certain features of construction and combination of parts as will be hereinafter described and pointed out in the claim.

Figure 1, of the accompanying drawings is a view in perspective of a fragment of roofing illustrating my invention; Fig. 2, an end view or transverse section. Fig. 3, is a perspective of a fragment of a sheet having a wide upturned flange showing a locking tongue out therefrom. Fig. l, is a similar view of the anchor showing a corresponding locking tongue. Fig. 5, is a similar View of a fragment of adjoining sheet, showing a turned up flange that is narrower than that shown in Fig. 3. Fig. 6, is a similar view showing the three elements of construction in position, the wide upturned flange and the anchor locked together by the horizontal tongue.

Similar letters of reference indicate correspondin g partsin allot the figures of the draw- Ings.

A represents a sheet of metal roofing having a turned up flange portion b, preferably about two inches high, and is for the purposes of this application called the wide flange or turned up portion.

O is the anchor, and is of the form shown, having a turned up portion (1 to correspond with the flange b of sheet A, and a horizontal portion 6 that is secured to the sheeting board by nails in the usual way.

F represents the adjoining or next sheet in the process of construction, on which is provided an upturned flange g which will be designated as the narrow flange.

Fig. 6 shows the parts all in position. to be turned to finish the seam as shown in Fig. 1.

The particular feature of my invention relates to and consists in providing means for securing the top portions of the flange b and the top portion d of the anchor together, and to accomplish this, triangular tongues ash and it cut with a tool provided therefor from the flange b and anchor as shown in Fig. 6, the free ends of which are turned over on the anchor in position horizontally with the sheets A, by which the flange b is secured to the anchor, before the same are turned down to complete the seam as shown in Figs. 1 and 2. I cut the tongues out horizontally with the flange b so that when the tongues are turned over on the anchor, the line on which they are folded will be perpendicular to the roof and the sheet A cannot be raised out of position, the tongue 7t of the flange b in the-aperture k in the anchor will engage the upper side of said aperture and prevent the raising of the sheet. The flanges are now turned down to complete the seam, the tongues folded back on the anchor, the flange b and the anchor turned over and down upon the narrow flange g, with the tongues concealed between the flange g and the anchor, in which position the anchor will serve to hold both of the sheets A and F to the sheeting.

Having thus fully described the nature and object of my invention, what I claim,and desire to secure by Letters Patent, is-- The combination with the sheets A and F having turned up flanges b and g, of the anchor C and triangular tongues h and it cut from the flange b of sheet A and the vertical portion 01 of the anchor O, the free ends of which are folded back on the anchor on a line perpendicular to the roof, substantially as described.

In testimony whereof I have hereunto set my hand this 12th day of October, A. D. 1892.

WILSON O. BERGER.
